Bookies back Billi for boot

The 25-year-old, from Middlesex, is odds-on favourite to follow Shabnam and Seany to become the third person evicted from the show, according to bookies Paddy Power.

They have the model at 1-50 to get the chop, with fellow nominees Carole and Tracey on 25-1 and 11-1 respectively.

Billi has rubbed a few housemates up the wrong way since he entered the reality programme two weeks ago. Ziggy in particular has not warmed to the model and ended up dumping his in-house girlfriend, Posh Spice wannabe Chanelle, after she and Billi appeared to be openly flirting.

The pair eventually reconciled, but Ziggy still nominated Billi for the chop, saying: "He's played some games, he's trying to play people off each other."

The model probably gained some points on Wednesday night, however, when he faced up to two-faced Charley. The pair started bickering and Billi told her she was going to be the "most hated contestant ever" when she leaves the house.

She countered with a jibe about his teeth, to which he replied: "You look like a horse, mate" and sarcastically added: "Yeah, you're a big star Charley, you're a big star. You should have been on Celebrity Big Brother."

Ziggy and Jonathan have both said they want to leave the house in recent days. Housemates were stunned into silence and some cried when Jonathan said on Wednesday that he wanted to walk. But by yesterday he had decided to stay and tough it out, to Carole's delight.

Also on Wednesday, Ziggy went into the Diary Room and made a request to leave after rowing with Charley about her calling him a pervert. He told Big Brother Charley was "very, very young" with "too much of a mouth on her" and added that he was disgusted at someone's suggestion that she was so aggressive because she had fancied him when he first moved into the house.

Big Brother instructed him to sleep on it, but he insisted this would not change his mind - although he appeared not to have left the house by last night.

Tensions have also been high this week after the housemates opted out of a challenge which would have meant them staying awake for three days. They have had to live off a basic food supply, but yesterday had the chance to win a "non-slop" breakfast if they wrote a song and performed it for Big Brother.

In half an hour, they had created their masterpiece - which had to contain a solo from each housemate. It included the immortal lines: "I'm Amanda. Loves pink. I'm girly don't ya think?" and "I'm Tracey, I'm a raver, I'm a hardcore cheesy quaver."

Charley modestly came up with the lines: "I'm Charley, I'm hot, I'm everything you're not" while Ziggy's section including "Great hair. The girls they love to stare".

They won the task and received juice, tea bags, milk and cereal - and a single sausage, causing a row about how to divide it up. Laura eventually took the practical option and simply cut it up into pieces so that every housemate could have a morsel.
